2.3 Foam commissioning (with factory settings)
For use in applications with a significant buildup of foam.
Performing foam calibration
1. Mount the sensor according to the installation conditions (see Chapter 1.4 "Installation conditions"
and 1.7 "Mounting the coaxial tube")
2. Log into expert mode (see Chapter 5.1 "Expert mode")
3. Empty the tank completely
The probe rod must be completely free from medium and foam.
○
Buildup must be removed from the probe.
○
The end of the probe must not be fixed to the bottom of the tank.
○
4. Select the measuring mode
Access the EXPRT-CONFIG-MeasMd menu using the arrow and Set pushbuttons, and configure
○
to HiAcc.
5. Perform empty calibration
Access the EXPRT-FOAM-CalEmp menu using the arrow and Set pushbuttons.
!CalOk: proceed to step 6.
○
!faild: Ensure that the tank is empty and repeat step 5.
○
6. Fill with medium (without foam) until the probe is covered by at least 200 mm. The maximum level
must remain 200 mm from the process connection, however.
7. Adjust the sensitivity
Exit the EXPRT menu with the ESC pushbutton. The LFP must now display a valid measured value.
If the measured value is invalid, adjust the TrsHld value in the EXPRT-CONFIG menu.
Access the EXPRT-CONFIG-TrsHld menu using the arrow and Set pushbuttons.
